Abstract
Compact and low‐cost spectropolarimeters are desirable in many fields for probing the wavelength‐dependent polarization state of light. Conventional spectropolarimetry systems use bulky, free‐space optical components or require at least four spectrometers. Herein, a chip‐scale spectropolarimeter capable of reconstructing input Stokes spectrum with a single spectrometer is demonstrated. All the components, including a surface polarization splitter, a channeled spectrum generator, and a Vernier spectrometer, are monolithically integrated on a footprint of 0.3 mm × 1.5 mm. The device is implemented using a complementary metal oxide semiconductor (CMOS)‐compatible fabrication process and achieves a resolution of 0.1 nm across a wavelength range of 56 nm near 1550 nm. This work provides a path toward on‐chip, low‐cost Stokes spectroscopy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
